Description
Technical field
The present invention relates to a kind of HPLJ9000 of being applicable to series printer coupling between organic light guide drum, magnetic roller, charging roller, powder delivery cutter, cleaning doctor and the ink powder in the cartridge.
Background technology
At present, compare with other models, the page or leaf output of this cartridge will have more 3～10 times, and the electrical property of its thickness requirement to the photoconductor drum coating, abrasion resistance properties and charging roller is obviously different.In the tradition, this series cartridge factory formula only carries out simple proportioning, consideration organic light guide drum not yet in effect, the magnetic roller, charging roller, powder delivery cutter, the mutual performance impact of cleaning doctor and ink powder, cause quality uneven: effective usage ratio of ink powder is on the low side, and the whole life-span can produce the useless powder of the not transfer printing of the surplus powder that does not use of 25～40g and 25～40g, produces waste and pollutes; The print quality discreteness is bigger and unstable, especially in the middle and later periods in cartridge life-span, and because of each accessory depletion occurs often owing to mismate, the phenomenon of function diminuendo, the print defect showed increased can't satisfy the printing demand; The single page powder consumption is more than 0.04g, and can 980g～1000g amount of toner can only print 29000～30000 pages, causes overall cost too high.
Summary of the invention
In order to prolong the serviceable life of cartridge, reduce and print cost, economize on resources, the fixing coupling of producing of a kind of cartridge provided by the invention, by matching specific organic light guide drum, magnetic roller, charging roller, one-component negative polarity magnetic ink powder, powder delivery cutter and cleaning doctor, make each assembly property reach optimum matching, can overcome the deficiency that present factory formula brings.
The present invention realizes by the following assembly of coupling:
1, organic light guide drum: be made up of aluminium base, the anti-reflection layer of conduction, charge generation layer, charge transport layer, the coating thickness general thickness is controlled at 35 μ m～45 μ m, the charge generating layer THICKNESS CONTROL should be controlled at 32.5～41.5 μ m, coating unevenness＜1 μ m at 2.5 μ m～3.5 μ m, charge transfer layer thickness; Its coating surface resistance＞170M Ω; Charging roller to its charging after, the electric charge output layer can be filled and be evenly distributed-the initial potential V0 of 650V high-pressure electrostatic lotus; Have suitable light sensitivity E1/2, required exposure should be controlled 0.18 μ J/cm when its current potential was decayed to half and is 1/2V0 by initial potential V0
2～0.25 μ J/cm
2In the scope; The electric charge output layer produces the exposure current potential VL of 140V～150V after accepting laser radiation, form and initial potential-500V current potential difference, and and the magnetic roller between produce rational electric field difference, the ink powder that carries on the magnetic roller can be attracted in right amount; In the potential decay speed that reaches under the unglazed radiation situation under the surface potential situation of setting, promptly dark decay rate DDR is controlled at the scope of 10V/S～15V/S; The coating surface resistance value can guarantee that coating keeps state of insulation under the illumination that does not reach energy, makes organic light guide drum automatic exposure under the exposure need state, the fatigue phenomenon that overexposure causes can not occur not having; The organic light guide drum external coating is at charging roller, ink powder, medium, the long-term circulation wearing and tearing of cleaning doctor down, its rate of depreciation＜1 μ m/ organic light guide drum rotates 200,000 circles, to guarantee can not produce considerable influence to the photoelectric properties of drum;
2, magnetic roller: magnetic has good uniformity, and ink powder can evenly be adsorbed; With 240 order white fused aluminas coating surface being carried out the high speed dash coat under the air pressure of conductive coating roughness by 0.14mpa forms, roughness increased to and keep Ra=1.6 μ m～2.5 μ m, the electric charge of even, sufficient acquisition-650V when toner particles is rubbed between powder delivery cutter and magnetic roller, the jacket thickness at magnetic roller two ends is 1.55mm ± 0.01mm, distance between organic light guide drum coating and magnetic roller coating is controlled in 1.55mm ± 0.01mm scope, guarantees that the toner particles of appropriate amount is participated in development;
3, charging roller: resistance value between coating and metal shaft=12M Ω～25M Ω, make at the appointed time the organic light guide drum surface have density suitably, be evenly distributed-650V high-pressure electrostatic lotus; Value=HD43 ° ± 3 ° A of rubber sleeve and conductive sponge overall hardness, elasticity are good, and under the pressure of former powder box location, power spring, and the pressure control that all surface of contact produce between the organic light guide drum is in 5N～5.5N scope; The rate of depreciation that the charging roller surfaceness causes the organic light guide drum surface should be rotated 100,000 circles less than 0.1 μ m/ organic light guide drum; Ra=0.11 μ m～0.14 μ m; Have certain electrical property setting range,, have certain stability in the changing environment scope that temperature is 5 ℃～35 ℃, to eliminate, to reduce or to remedy the influence of environmental factor organic light guide drum cloth electricity at relative humidity RH10%～90%; When mains fluctuations, the output characteristics of accepting of charging roller remains unchanged substantially; The photoelectric properties fatigue that local voltage is too high, organic light guide drum caused local damage (punctures) or acceleration organic light guide drum can not appear in charging roller and load (air-gap, optical conductor etc.) impedance phase coupling;
4, one-component negative polarity magnetic ink powder: constituent is a carbon black, magnetic oxide, resin, the ratio of lubricant and adjuvant is respectively carbon black 2%, magnetic oxide 41%, resin 51%, lubricant 4%, adjuvant 2%, make greasy property, flowing property, the colourity of ink powder reach optimum condition, the charged ability of unit volume ink powder reaches carried charge=300uc/g～350uc/g; Toner particle diameter is even, distribution range is controlled at above 1.5%, the 6.5 μ m of following 1.5%, the 8 μ m of 5 μ m～7.5 μ m more than 90%, and the toner particles of participating in development and finally transfer printing is reached more than 90%; Softening point is 149 ± 2 ℃; But flowing property degree of scatter＞40% between the toner particle under rated condition, the nominal value limit deviation is 20%; Apparent density is 18.8g ± 1g/cm
3
5, powder delivery cutter: by stainless iron or etc. hardness rustless metal bracing frame, the PU material is magnetic roller support face and rubbing surface, require PU material corner angle, the rubbing surface flatness is good, thickness is even, hardness=HD71 ° ± 2 ° A, and elasticity is good, can be evenly when making between ink powder powder delivery cutter and magnetic roller friction, the electric charge of acquisition-650V fully, and can be uniformly gap by powder delivery cutter and magnetic roller, the thickness on pressure control friction back absorption left magnetic roller surface is 0.3 ± 0.01mm, and the magnetic roller rotates 300,000 circles or places 5 years powder delivery cuttves and elastic force depletion can not occur;
6, cleaning doctor: by stainless iron or etc. hardness rustless metal bracing frame, the PU material is that magnetic roller support face and rubbing surface are formed, require that PU material corner angle, rubbing surface flatness are good, thickness evenly, hardness=HD75 ° ± 3 ° A and elasticity is good, and form suitable pressure between the organic light guide drum, can be good at after the organic light guide drum surface development but the ink powder of transfer printing cleaning is clean, organic light guide drum rotates 100,000 circles or places and elastic force depletion can not occur in 5 years.
